This conversation seems to come up every now and again and lemmy seems to split between two camps:

• students, especially low income students who can’t afford their own devices, will use devices to do things kids do (yes, this includes porn)
• schools, as part of their duty to provide a safe learning environment, have a responsibility to provide some level of filtering and content monitoring

Where that line gets drawn has to be an active conversation between schools, parents, and students. But this conversation often delves into “BuT tHiNk Of ThE cHiLdReN!”
